Traffic tie-ups can't always be prevented. But with Garmin's GTM 20, they can often be avoided.
The GTM 20 is an integrated FM-band receiver, antenna, and cigarette lighter adapter that provides real-time Traffic Message channel (TMC) data to compatible Garmin GPS navigation products-which then depict and identify problem areas on their moving-map displays. Available in a fast- growing number of cities throughout North America and Europe, this TMC data gives prompt, accurate notification of accidents, road construction, police, or emergency action, etc.-so drivers can visually monitor traffic flow and, if necessary, select an alternate route.
The TMC traffic alerting system works on an FM sideband signal which utilizes RDS (Radio Data Service) technology. Digitized and coded real-time traffic broadcasts are received via a "silent" FM data channel-which means that drivers can still listen to music or news programming on their car radios, without interference from the incoming FM traffic data transmissions. In most areas, depending on the service provider, TMC traffic broadcasts are continuous-there's no waiting for scheduled traffic news updates or random alerts. With the GTM 20, you see traffic developments in real-time, as they happen, so you can make the right decision sooner. The system will alert you when a traffic problem is on your route and propose an alternate route to avoid the incident.
Unlike the GTM 10 and 11, the GTM 20 is an all-in-one antenna, traffic receiver, and 12-volt cigarette adapter.
